PROCEDURE
9.2. External wiring procedure (Fig. 9-5)
Power supply: Single phase 220/230/240 V, 50 Hz 220 V, 60 Hz
Note:
Power supply input: Outdoor unit only. Connect the lines (C), (D) in accord-
ance with the terminal block names to ensure correct polarity.
As for lines (C), S1 and S2 are for connecting the power source.
And S2 and S3 are for signals. S2 is a common cable for the power source
and signal.
When using twisted wire for the wiring, the use of round terminal is required.
*1 Refer to the installation manual of the outdoor unit.
*2 Max 45 m (“Outdoor unit - Branch box
#
1” plus “Branch box
#
1 - Branch box
#
2”).
If 2.5 mm
2
used, Max 55 m.
Notes: 1. Wiring size must comply with the applicable local and national code.
2. Power supply cords and Indoor unit/Branch box/Outdoor unit con-
necting cords shall not be lighter than polychloroprene sheathed
flexible cord. (Design 60245 IEC 57)
3. Install an earth line longer than power cables.

Warning:
In case of A-control wiring, there is high voltage potential on the S3 terminal caused by electrical circuit design that has no electrical insulation between power line
and communication signal line. Therefore, please turn off the main power supply when servicing. And do not touch the S1, S2, S3 terminals when the power is
energized. If isolator should be used between outdoor unit and branch box/indoor unit and branch box, please use 3-poles type.
Caution:
After using the isolator, be sure to turn off and on the main power supply to reset the system. Otherwise, the outdoor unit may not be able to detect the branch
box(es) or indoor units.
